Tongue Tricks

Dean and Sam looked at one another in complete confusion as they heard slurping and other strange noises coming from their room. They looked around to see Castiel slowly appear, flicking his tongue around like a maniac.

"Holy crap! It's Linda Blair!" Dean laughed, earning a punch on the arm from Sam.

"Uh…Cas…what the hell are you doing?" Sam asked, backing away when the angel started curling his tongue around and flicking it about again.

"I'm trying to see what different things I can do with my tongue." Castiel said, "I was in here last night and I saw Dean do something with his tongue…he swirled it around the inside of his closed mouth, and I tried it and discovered I could do it too!"

Dean raised an eyebrow and then backed away looking disgusted when that rather large tongue reappeared and Castiel sighed while moving it in and out of his mouth making a repetitive: "Fffth" noise. Then the angel sat on Dean's bed and let out a low sound from his throat, waggling the tongue about and making a "Lalalalalalalala" sound.

Sam coughed uncomfortably and put his hand on Dean's shoulder before grabbing the keys to the Impala.

"All yours, man." He laughed sprinting out of the door before Dean could protest.

The older Winchester sighed and shook his head as he heard the car speeding away.

"Dean…you do things with your tongue when you kiss girls." Castiel said, "How do you do that? It seems to make them very happy."

Dean couldn't help but moan softly when he saw Castiel run that tongue over his top lip, unintentionally seductively.

"Are you alright, Dean?" Castiel asked, giving Dean a quizzical look before repeating the movement.

Dean moved closer and sat beside the angel.

"Let me show you what I do to girls with my tongue." Dean whispered huskily, wrapping a hand around the nape of Castiel's neck and pulling him in for a tongue filled kiss.

Castiel froze, but suddenly melted into the kiss as Dean slowly taught him how to move his lips and tongue without breathing a word. Pulling away from the kiss, Dean was left panting, wanting more.

Then everything sank into place. This was the empty feeling he'd been missing for so many months. Castiel was the missing piece of him he'd been searching for, and God did that notion scare him. Castiel chased his lips and tried using his tongue to lead, following Dean's instruction quite well. Pulling back, their foreheads rested together.

"Dean…" Castiel whispered, "You're an amazing kisser."

"I love you." Dean replied, quicker than he ever could've anticipated.

Shit. Fuck. Damn...OH WHY DO I ALWAYS FUCK THINGS UP?

Castiel studied him for a moment before smiling so radiantly Dean's breath caught.

"I love you." Castiel repeated, "And your tongue tricks."

Dean grinned widely, and then cheekily before he leaned in for another kiss, removing the angel's trenchcoat and suit jacket, breaking the kiss to sling the tie over his head. Dean's outer shirt came off and fell to the floor with accidental grace, followed by Castiel's dress shirt and Dean's t-shirt. The thuds of shoes falling to the floor were heard, and then two belts were unbuckled, one pair of jeans and another pair of dress pants fell to the floor with the rest of the clothing. Castiel parted his legs for Dean to lie between and the couple continued their kissing and tongue-trick escapade.

"Dean…" Castiel said when they needed to come for air, "Who is Linda Blair?"

-The End-
